appearance, fit and adherence to specified tolerances are observed. Particular attention shall be given to
neatness and thoroughness of marking parts, plating, welding, soldering, riveting, staking, and bonding.
The visual examination under 3x magnification shall include examination of each retention cavity for
molding discrepancies, retention features, and excessive adhesive. The connectors shall be free from
crazing, cracks, voids, pimples, chips, blisters, pinholes, sharp cutting edges, burrs, and other defects that
will adversely affect life, serviceability, or appearance.
